A public health warning's been issued over a vaping product with potential to cause lung injuries

The Ministry of Health has lodged a product warning about Suntree Vanilla Cream.

It contains too much of a chemical associated with what's called popcorn lung -- containing more than four times the legal amount of diacetyl .

The Health Ministry says about 300 are understood to have been sold in the past 17 months.

Anyone with the product should stop using it, because a recall from stores, is under way.
